How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read cubic yards, tons, and cubic feet results.
What it does The Road Base Calculator turns the three dimensions you input—length, width, depth—into three useful measures: cubic yards, tons (using the standard 1.4 US tons per cubic yard), and cubic feet. Knowing the volume in cubic yards tells you how many dump‑truck loads to order; the ton estimate helps you budget material costs; cubic feet is handy for comparing with other building‑site calculations. Why it matters Ordering too little forces a costly second delivery, while ordering too much wastes money and space. The instant results let you plan accurately before you call a supplier. How to read the results
- Cubic yards – the primary unit for road‑base orders.
- Tons – multiply cubic yards by 1.4; the calculator does this for you.
- Cubic feet – useful for on‑site volume checks.
Pro tips
- Add 5‑10% extra for compaction loss.
- Round up to the nearest whole cubic yard when ordering.
- Check local supplier minimum order weight.
- Double‑check depth measurement; a 1‑inch error changes volume noticeably.
Real-life examples
- A homeowner preparing a new driveway needs to know how much crushed stone to order.
- A landscaper installing a garden path wants to budget material costs accurately.
- A small contractor building a garage ramp must match supplier dump‑truck sizes.
Case study
John needed a 12‑ft × 8‑ft driveway 4 in deep. Using the calculator he saw he required 2.67 cubic yards, about 3.7 tons. He ordered 3 cubic yards, saving a second delivery and $120 on material.
